JOSEPH M. ERTS AND JOHN MILLER, OF POUGHKEEPSIE, NEW YORK.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 645,557, dated March20, 1900.

Application filed June 19, 1899. Serial No. 721,075. (No model.)

To all whom it may concern.

Be it known that we, JOSEPH M. ERTS-and JOHN MILLER, citizens of theUnited States, residing at Poughkeepsie, New York, have invented certainnew and useful Improvements in Acetylene-Gas Generators, of which thefollowing is a specification.

Our invention relates to improvements in acetylene-gas generators; andthe object of the invention is to provide a generator which may bereadily opened to gain access to the interior and one in which the coveror upper portion of the generator is provided with a water-chamber forkeeping the walls cool, whereby any moisture in the gas will becondensed. e have also aimed to provide a water seal between the partsof the generator, whereby all escape of gas is absolutely preventedwithout necessitating the care in making the joints which is necessaryin most generators in use. 7

To this end the invention consists, primarily, in a generator having awater-chamber in the cover or upper portion thereof.

It further consists in a generator having a removable cover with a waterseal between said cover and the body of the generator.

It still further consists in the construction and arrangement of theparts herein described, and pointed out in the claim.

The invention is illustrated in the accompanying drawings, in which-Figure 1 represents a central vertical section through the generator,and Fig. 2 is a transverse section on line 2 2 of Fig. 1.

The body of the generator is indicated at 3 and the removable cover at4. The cover, as will be observed, is provided with an annular dependingwater-chamber formed by the concentric walls 5 and 6, the inner walls 6being connected at the top by the horizontal wall 7 whereby a closedchamber 8 is formed, into which water is introduced by a The body of thegenerator is designed to be filled with water up to the level indicatedin the drawings, and it will be observed that a perfect water seal isthus formed, and it is thus unnecessary to use any particular care inmaking a close fit between the cover and body of the generator.

The carbid is contained in a vessel 10, which is removably sustained bythe frame or support 11, connected with the body of the generator, thecarbid-receptacle being open only on its upper side. Water is suppliedto the carbidreceptacle by a supplypipe 12, extending from a point abovethe generator downwardly below the lower edge of the cover, then inward,as shown at 12 then upward, as at 12", and then laterally inward fromthe edge of the carbid-receptacle, where it terminates in a spray-nozzle12. The portion of the pipe which carries the spray-nozzle is providedwith a hingejoint 12 whereby it may be swung out of the way to permitthe removal of the carbid-receptacle. The gas is conducted from thegenerator by an outlet pipe 13, which extends from above the water-valveof the generator downward below the lower edge of the cover and thenoutward to connect with a gas-holder of the ordinary or any desiredform, (indicated at 14.) r

In order that the cover. may be kept cool, We provide awater-circulating pipe 15, which extends from the upper portion of thecover downward to the lower end of the depending portion.

From the above description it will be understood that the gas generatedby the carbid will rise and strike against the water-cooled surface ofthe cover and, being chilled thereby, any moisture in the gas will becondensed and fall back upon the carbid.

We claim as our invention-- In combination, the body portion, the coverhaving an annular rim resting upon the upper edge of said body portionand having an annular water-chamber depending within said body portion,supports extending up within said annular water-chamber, acarbid-receptacle removably supported thereby and means for feedingwater to said receptacle and withdrawing the gas, substantially asdescribed.

In testimony whereof we affix our signatures in presence of twowitnesses.

JOSEPH M. ERTS.

JOHN MILLER.
